Answer:

y = x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1, thus

y = x + c ← is the partial equation

To find c substitute (5, 3) into the partial equation

3 = 5 + c ⇒ c = 3 - 5 = - 2

y = x - 2 ← equation of line

If 6-x=2(x-6) what is the value of x? need steps!!

V125BC [204]

6 - x = 2(x - 6)

the first step, following PEMDAS, is to distribute the 2 to the inside of your parentheses:
6 - x = 2x - 12 ... subtract 2x
6 - 3x = -12 ... subtract 6
-3x = -18 ... divide by -3
x = 6 is the answer

ANSWER

Option B

and

Option D.

EXPLANATION

The graph of the function has an amplitude of 2 and a period of

$\frac{2\pi}{3}$

Choose all the equation that has an amplitude of 2 and a period of

$\frac{2\pi}{3}$

These are:

$y = 2 \sin3(x - \frac{2\pi}{3} )$

and

$y = 2 \sin(3x)$

The second and the last options are correct.

During two years, the population of birds of an island became 7 times more than before. If the first year increase in the popula

nordsb [41]

Answer:

The percent increase of the second year is 400%.

Step-by-step explanation:

Consider the provided information.

Let the population of birds was x.

After 2 years the population becomes 7 times more than before.

Therefore, after 2 years population is 7x.

In first year increase in the population was 40%.

Population after 1st year = x + 40% of x

Population after 1st year = x + 0.40x

Population after 1st year = 1.4x

The population increase from 1st year to 2nd year is: 7x-1.4x=5.6x

Thus the percentage increase is:

$\% increase=\frac{5.6x}{1.4x}\times100=400\%$

Hence, in second year the population of birds increase by 400%.
